    NSString * fooString = @"FOOSTRING";
    NSMutableArray *list = [NSMutableArray array];
    for (int i=0; i<fooString.length; i++) {
        [list addObject:[fooString substringWithRange:NSMakeRange(i, 1)]];
    }
    NSLog(@"%@", list);
    

    NSLog output:

    (
                                                      F,
                                                      O,
                                                      O,
                                                      S,
                                                      T,
                                                      R,
                                                      I,
                                                      N,
                                                      G
                                                      )

    How about

    [fooString cStringUsingEncoding: NSUTF8StringEncoding];

    you can also use [NSString getCharacters:(unichar array) range:(nsrange)]; you will get an easy to manipulate array.I needed it my self and found it on this link
